Мониторинг, управление и защита схем питания
Analog Devices’ monitor, control, and protection family offers solutions for the analog and digital power management functions demanded by high performance systems. Monitoring functions include voltage supervision for reset generation, as well as ADC-based digital measurements of voltage, current, charge, power, energy, and temperature. For power control, devices can turn on/off power supply rails and also sequence, track, trim, and margin them with precision. Surge stoppers, hot swap, and ideal diode controllers protect against abnormal voltages and currents. Robust power over Ethernet (PoE) controllers allow up to 90 W of power to be managed and transferred between power sourcing equipment (PSE) and powered devices over low cost Ethernet cables. Our portfolio incorporates high accuracy, offers varying levels of functional integration, and features analog or digital configuration.
